What makes you think they would have gone along with "the cheapest bailout in history" line?
It's very easy to look back on fiscal policy and say "that was a decision which led to an unsustainable fiscal and economic situation for the sovereign", but when you're going through it, that clarity does not exist. Sustainability is a bit like a structural deficit: you only ever really understand it in hindsight, the further you are from the time series in question, and even then there are a myriad of interpretations of what sustainability actually means or how its can be arrived at in empirical terms.
Don't forget that despite what you or I may think today at 10am on the 26th of May 2012, we are being told that Ireland's debt level, which is expected to peak at 119% of GDP is still sustainable. We may not be told the same in one or two years time.
